GTK & malloc(): memory corruption

chabayo

...da ich keine Ahnung habe warum mich dash umwirft, hier der Text:

void nautic_hashset_add ( GtkButton *button , main_data *data ) {

	data->m = malloc ( sizeof ( hash_set ) );
	for ( data->i = 0 ; data->i++ < sizeof ( hash_set ) ; strcpy ( data->m++ , "\0" ) );

	data->hashset->next = ( hash_set * ) data->m;
	data->n = data->hashset;
	data->hashset = ( hash_set * ) data->m;
	data->hashset->previous = data->n;

	data->hashset->hashbox = gtk_hbox_new ( FALSE , DEF_BOX_SPACING );
	gtk_box_pack_start ( GTK_BOX ( data->box ) , data->hashset->hashbox , FALSE , TRUE , DEF_BOX_PADDING );
	data->hashset->label = gtk_entry_new ( );
	gtk_box_pack_start ( GTK_BOX ( data->hashset->hashbox ) , data->hashset->label , TRUE , TRUE , DEF_BOX_PADDING );
	data->hashset->data = gtk_entry_new ( );
	gtk_box_pack_start ( GTK_BOX ( data->hashset->hashbox ) , data->hashset->data , TRUE , TRUE , DEF_BOX_PADDING );
	data->hashset->new = gtk_button_new_from_stock ( "gtk-new" );
	gtk_box_pack_start ( GTK_BOX ( data->hashset->hashbox ) , data->hashset->new , FALSE , TRUE , DEF_BOX_PADDING );
	g_signal_connect ( G_OBJECT ( data->hashset->new ) , "clicked" , G_CALLBACK ( nautic_hashset_add ) , data );
	data->hashset->delete = gtk_button_new_from_stock ( "gtk-delete" );
	gtk_box_pack_start ( GTK_BOX ( data->hashset->hashbox ) , data->hashset->delete , FALSE , TRUE , DEF_BOX_PADDING );
	g_signal_connect ( G_OBJECT ( data->hashset->delete ) , "clicked" , G_CALLBACK ( nautic_hashset_delete ) , data );

}

...das bringt bei mir in der 12. Zeile...

gtk_box_pack_start ( GTK_BOX ( data->box ) , data->hashset->hashbox , FALSE , TRUE , DEF_BOX_PADDING );

...diesen Fehler:

*** glibc detected *** malloc(): memory corruption (fast): 0x0824c990 ***

Hat mir dazu jemand ne Stuetze??

...mh...Zeile 4 hat wohl etwas die Grenze gesprengt.

GPC

for ( data->i = 0 ; data->i++ < sizeof ( hash_set ) ; strcpy ( data->m++ , "\0" ) );

Woah, du hältst den Code auch gern kompakt, heh? Würde mich wundern, wenn du den in 'n paar Wochen noch lesen kannst

...gaebs ne Kluge alternative??

Na ja, zumindest den Kopf der for-Schleife nicht als Anweisungsblock (von inkrement und dekrement sei mal abgesehen) zu missbrauchen würde schon einiges helfen
